Accessing index.html file on SD card

[sebastian1967]

Hello,
I should need to access to my web server files that are stored on a SD card. In particular I would open the index.html page. How can I do this? The code from wich I'm starting is here under. In particlar I don't understand how to change this part here:

ResourceNode* nodeRoot = new ResourceNode("/", "GET", [](HTTPRequest* req, HTTPResponse* res) { res->println("Secure Hello World!!!"); });

Full code here:

`#include <WiFi.h>
#include <HTTPSServer.hpp>
#include <SSLCert.hpp>
#include <HTTPRequest.hpp>
#include <HTTPResponse.hpp>

using namespace httpsserver;

#include "FS.h"
#include "SD.h"
#include "SPI.h"

// Replace with your network credentials
const char* ssid = "ESP32-Access-Point";
const char* password = "123456789";

SSLCert* cert;
HTTPSServer* secureServer;

bool SD_present;
int chipSelect = 5;

void initSDCard() {
if (!SD.begin(chipSelect, SPI, 4000000U, "/sd", 10U, false)) {
Serial.println(F("Card failed or not present, no SD Card data logging possible..."));
SD_present = false;
}

uint8_t cardType = SD.cardType();

if (cardType == CARD_NONE) {
Serial.println("No SD card attached");
return;
}

Serial.print("SD Card Type: ");
if (cardType == CARD_MMC) {
Serial.println("MMC");
} else if (cardType == CARD_SD) {
Serial.println("SDSC");
} else if (cardType == CARD_SDHC) {
Serial.println("SDHC");
} else {
Serial.println("UNKNOWN");
}
uint64_t cardSize = SD.cardSize() / (1024 * 1024);
Serial.printf("SD Card Size: %lluMB\n", cardSize);
}

void setup() {
Serial.begin(115200);
initSDCard();
delay(1000);
// Connect to Wi-Fi network with SSID and password

Serial.println("Creating certificate...");

cert = new SSLCert();

int createCertResult = createSelfSignedCert(
*cert,
KEYSIZE_2048,
"CN=myesp.local,O=acme,C=US");

if (createCertResult != 0) {
Serial.printf("Error generating certificate");
return;
}

Serial.println("Certificate created with success");

secureServer = new HTTPSServer(cert);

Serial.print("Setting AP (Access Point)… ");
// Remove the password parameter, if you want the AP (Access Point) to be open
WiFi.softAP(ssid, password);

IPAddress IP = WiFi.softAPIP();
Serial.print("AP IP address: ");
Serial.println(IP);

/* server.on("/", HTTP_GET, [](AsyncWebServerRequest* request) {
request->send(SD, "/index.html"); //, "text/html");
});

server.serveStatic("/", SD, "/");

server.begin();*/

ResourceNode* nodeRoot = new ResourceNode("/", "GET", [](HTTPRequest* req, HTTPResponse* res) {
res->println("Secure Hello World!!!");
});

//server.serveStatic("/", SD, "/");

secureServer->registerNode(nodeRoot);

secureServer->start();

if (secureServer->isRunning()) {
Serial.println("Server ready.");
}
}

void loop() {
secureServer->loop();

delay(10);
}`
